discussed as a part of this chapter but are intended to provide an idea of the factors
that the software design should address for it to be robust.
The Design phase maps to the Design and Implementation phase of the software
development cycle. The software architecture road map, design requirements, and
use cases are among the artifacts that are used in this phase.
